To use as ringtone on your iPhone open the m4r audio file with iTunes and it will automatically be put in the "Ringtones" folder. Then sync your phone. You may need to check the "Sync ringtones" box under the "Ringtones" tab in iTunes for your iPhone. (Unfortunately if the sound clip is over 40 seconds it will not work because iTunes puts a limit on it.)
